Bug Description
lock/lock0lock.c says
/* Restricts the length of search we will do in the waits-for
graph of transactions */
#define LOCK_MAX_
/* Restricts the recursion depth of the search we will do in the waits-for
graph of transactions */
#define LOCK_MAX_
I would like these to be configurable global variables. Can we also set the transaction's status so you see "checking for deadlock" in SHOW INNODB STATUS? That way, a user who increases these variables (or starts running into the deadlocks caused by them) will have a hint about what is happening.

Since Percona Server has replaced percona-patches, I'm moving this Wishlist item over to Percona Server and marking as "Won't fix" for percona-patches
